TECHNOLOGY & BUSINESS — Anthropic is gaining significant ground against OpenAI in the United Kingdom, with fresh spending data suggesting that businesses are increasingly choosing Claude over ChatGPT for their artificial intelligence needs.
Anthropic accounted for as much as 54 percent of UK business spending on AI companies during the three months to July, compared with 27 percent for OpenAI, according to analysis shared with City A.M. The figures point to a major shift in the UK enterprise AI market, where OpenAI previously held a much stronger position.
The data also shows that AI adoption among UK businesses is accelerating rapidly, increasing the competitive importance of enterprise customers for the world's leading AI companies. 0
Anthropic Has Pulled Ahead
The latest figures represent a dramatic change from earlier in the year.
During the first quarter, OpenAI accounted for about 42 percent of business spending on AI companies, compared with 34 percent for Anthropic.
By the three months to July, Anthropic's share had risen to 54 percent while OpenAI's had fallen to 27 percent.
That means Anthropic's share was roughly twice OpenAI's during the latest period measured.
OpenAI Once Dominated the Market
The scale of the change becomes clearer when looking further back.
OpenAI accounted for as much as 70 percent of UK business spending on AI companies as recently as the second quarter of the previous year.
Anthropic's share at that time was only about 8 percent.
The movement from those figures to the latest data illustrates how quickly the enterprise AI market is changing.
Claude Is Becoming a Serious Business Competitor
Anthropic's Claude has increasingly been positioned as a tool for professional and technical work.
Businesses can use Claude for software development, research, writing, analysis and other knowledge-intensive tasks.
Anthropic has also focused heavily on developers and enterprise customers, areas where recurring business spending can be significantly more valuable than individual consumer subscriptions.
The company's strategy appears to be paying off as more organisations adopt its products.
AI Adoption Is Accelerating in Britain
The data does not only reveal a battle between two companies.
It also shows how quickly artificial intelligence is entering the UK business economy.
More than one in eight UK companies spent money on AI firms' services during the second quarter of the year, compared with roughly one in twenty at the beginning of the previous year.
That represents a substantial increase in the number of businesses willing to pay for AI tools.
Businesses Are Becoming More Selective
The early phase of generative AI was dominated by experimentation.
Companies wanted to understand what systems such as ChatGPT could do and employees often adopted tools individually.
The market is now becoming more commercial.
Businesses are increasingly deciding which AI systems deserve company-wide budgets, integrations and long-term contracts.
That makes product reliability, security, performance and cost increasingly important.
Enterprise AI Is Different From Consumer AI
Consumer popularity does not necessarily determine which AI company wins the business market.
A chatbot can have millions of individual users while another model can generate more revenue from a smaller number of companies.
Businesses may spend thousands or millions of dollars on AI systems, particularly when those systems become integrated into software development, customer service, research and internal operations.
That is why enterprise adoption has become such an important battlefield for Anthropic and OpenAI.
Anthropic Has Already Overtaken OpenAI in Some Business Measures
The UK data follows a broader trend in enterprise AI.
Ramp reported in April that Anthropic had surpassed OpenAI in the share of US businesses with paid AI subscriptions.
Anthropic reached 34.4 percent of businesses tracked by Ramp, compared with 32.3 percent for OpenAI.
Anthropic's business adoption had increased sharply over the preceding year, while OpenAI's growth was much slower. 1
The Battle Is Moving Beyond Chatbots
The competition between Anthropic and OpenAI is no longer simply about which chatbot gives the better answer.
Businesses are evaluating AI systems as infrastructure.
They want models that can write and review software, analyse large amounts of information, automate workflows and operate reliably inside existing business systems.
That creates a much larger opportunity than consumer chatbot subscriptions alone.
Claude Code Is Helping Anthropic
One important growth engine for Anthropic has been Claude Code, its AI-powered software development tool.
Anthropic says Claude Code has become its largest individual product revenue driver, with annualised revenue exceeding $2.5 billion as of February 2026.
The company also says business subscriptions to Claude Code have quadrupled since the beginning of the year.
Those figures demonstrate how coding agents are becoming an important part of the commercial AI market. 2
OpenAI Still Has Enormous Advantages
Anthropic's recent gains should not be mistaken for the collapse of OpenAI.
OpenAI still has one of the world's most recognisable AI brands, a massive consumer user base and a broad ecosystem surrounding ChatGPT.
It also has deep relationships with major technology companies and developers.
The UK spending figures show a shift in business spending, not the disappearance of OpenAI from the market.
Companies May Use Both
Another important trend is that businesses do not necessarily have to choose only one AI provider.
A company might use OpenAI for one application, Anthropic for another and Google's models for a third.
This multi-model approach reduces dependence on a single provider and allows businesses to select models according to specific tasks.
That could make the enterprise AI market considerably more competitive than the early chatbot era suggested.
Price Matters Too
AI companies are increasingly competing on cost as businesses become more sophisticated buyers.
A model that performs slightly better but costs substantially more may not necessarily win a large corporate contract.
Businesses have to consider the total cost of running AI across thousands of employees and millions of tasks.
That makes efficiency almost as important as raw model intelligence.
The AI Race Is Becoming a Business Race
The latest UK figures suggest that the AI competition is entering a new stage.
The question is no longer simply who can build the most impressive model.
It is increasingly about who can turn advanced models into products that companies are willing to pay for every month.
Anthropic appears to be making significant progress on that front.
What This Means for OpenAI
OpenAI now faces a more serious competitive challenge than it did when ChatGPT effectively defined the consumer AI market.
If Anthropic continues gaining business customers, OpenAI may have to compete more aggressively on price, model performance, enterprise features and specialised AI agents.
The company cannot rely indefinitely on ChatGPT's early lead.
The market is becoming much more crowded.
What This Means for Businesses
For companies buying AI services, the growing competition could be beneficial.
More serious competition can lead to better models, lower prices and more specialised products.
Businesses may also gain greater negotiating power as several AI providers compete for their contracts.
Instead of being locked into one platform, companies can increasingly compare performance and cost across multiple providers.
Our Perspective
Anthropic's rise in the UK is important because it challenges the assumption that OpenAI will automatically remain the default enterprise AI provider.
But the headline should be interpreted carefully.
The data measures business spending, not every form of AI usage, and it does not mean Claude has replaced ChatGPT among British consumers.
What it does demonstrate is that companies are becoming willing to move their money when another AI provider offers a better combination of performance, price and business value.
The AI race is entering its most interesting phase: having the biggest chatbot audience may no longer be enough. The winners will be the companies that become indispensable inside the world's businesses.
Conclusion
Anthropic has overtaken OpenAI in UK business AI spending, according to fresh data showing that Anthropic accounted for as much as 54 percent of spending on AI companies during the three months to July, compared with 27 percent for OpenAI.
The shift follows a dramatic change from earlier periods, when OpenAI held a dominant share of UK business AI spending.
Anthropic's progress is also consistent with broader enterprise trends. Ramp reported that Anthropic surpassed OpenAI in paid business adoption in the United States in April, highlighting the company's growing presence among corporate customers.
OpenAI remains a major force in artificial intelligence, but the latest UK figures show that its lead is no longer guaranteed. Anthropic has demonstrated that enterprise customers can change the balance of power—and the battle for corporate AI budgets is only beginning.
